You’re using this integration, right?
Yup. Just reflashed, can play Spotify from phone again, but not local files nor tts from hass. It tries to play from 192.168.4.X subnet (the one used for network config). No idea why.
In which folder did you place your media?
Finally I am playing TTS and local files from HASS. For some reason my settings in HASS Config -> System -> Network was wrong.
And I did now flash a Proto-board with ESPHome Media Player. It worx! It was only my Network settings in HASS, as previous post says. Thx!
What was wrong? Can you share how your configurations are?
